Good grief. Don’t buy into the “be presidential” narrative. I can put on high tops and a jersey, but it doesn’t mean I can play in the NBA.
That isn't the point. The point is that how one acts makes a difference in how people perceive that person. It's shocking to me that this is actually a point of contention here.
When I tried cases I wore a suit and tie, didn't use foul language, and didn't scratch my nuts in the presence of the jury. There was a reason for that.
